So, wouldn’t the tubes provided with the equipment be ones that the manufacturer thinks are pretty good?
Yes but you can do better than pretty good. Whether its worth the cost is up to you.
For the relatively low cost of the Freya+, they could include other, more costly tubes and charge a few hundreds bucks extra, and people would pay that. Right?
Schitt is about keeping costs down. It is important to them that they not raise the price by a few hundred bucks for any part.
